OFFICE CHICAGO, ILLINOIS RAIL :JOINT Application ledjSeptember 11, 1929. Serial No. 391,786.

This invention relates to improvements in rail joints of the type in which a. pair of rails seat upon a tie plate andare secured together by splice bars.

1It.`s an object of the. present invention to provide a rail joint Yinr which a splice bar.

which is bolted tothe `rail is securely held to the t-ie `plate by a Welded joint.

It is further an object of the present invention to provide an improved rail joint in which a pair'of splice barswhichconI 1ect/' th.eil

adjoining ends of 7a pair Iof lra'ilsare bolted` or otherwise secured to the rails and final`f\ ly welded joints'are formed between the'ltoes of the splice bars and projeotingyshoulders ofthe tie plate thereby providing additional strength in the connection and preventing rotating movement of the splice bars due to torsional stresses. Y y

Further and additional objects will be more readily apparent from the .following description in connection with the attached drawings in'whioh-w e y Figure 1 isla plan viewl of my improved rail joint;

Figure 2,/ is a side elevation of Figure l, showing portions of the ties 'in section, and

Figure 3 is af'transverse section through Y the'rail joint on the plan indicated by 3-3 l in Figure 1. f In the drawings, 10-10 are ties or sleepers upon which seats a` tie plate 11. JThe. tie plate 1'1 provides a chair or rest for the ends of rails 12-12. Each of the rails is of the usual shape including a head`13, web 14 and a base 15. The base l5 of the rail yseats on the tie plate 11 between projections 16-16 integrally formed with the tie plate. The projections 16 prevent lateraldisplacementof the rails.

' In order to connect adjoining ends of a pair of rails it is customary to employ angle bars or splice bars and I have here shown a pair of angle bars which are drawn into engagement with opposite sides of the rails. The upper portion of each of the splice bars as at 18., is enlarged to provide strength and bears against 4the inclined lower faces of. the rail head 13 in the manner indicated at 19-19. The lower rounded 'corners of the splice bars barsf are draw an gl/e bars, 'throu should be relative to thetie plate.

increased strength of the angle bars bear a surfaces of the r 20-20.

The splice bars are secured to the rails by means of bolt-s 21 fastened by nuts 22. Suitable bolt receiving openings 23 are formed in the rails and are lined 'up with holt openings 21-formed in Ithe splice bars It will be noted that `the bolt openings 23-21 are somewhat larger than the diameter of the bolts thereby permitting vtight engagemenbetween the splice bars and rails. The include depending angular flanges 25 which are provided at their outer andlower ends with integral toes 26 having vertical faces 27 arid horizontal lower faces 28.*@

will be 4a gainst the inclined upper ail `bases asl indicated at pparent that after the'angle n into tightre'ngagement with the railsf by securing the bolts 21 that the toes 2`6"will be ylifte with the tie plate.y The angle bars are held to the tie'plate by the usual spikes 29 which extendthrough spilge openings 30 in'the gh openings 3l. in the tie plate andn into the-wood ofjthe ties. The. spikes 29 have heads 32 which engage the upper faces-of the flanges 25.*.of the angle bars "and securely hold thevrails to the t' But it will be `obvious thatsome means provided to prevent rotation of the angle bars due to torsional stresses which are liable to loosen the spikes.l improvements in the present invention 'consist in providing welded joints between the angle bars\ and' the tie plate after the angle bars have been drawn to the desired' positions 'A preferred;embodiment'consists in providing integral shoulders 33 upwardly extending from the tie plate and parallel to the rail holding projections 16. The inner faces of the projections 33 are slightly irclined. The spaces between the inclined inner faces of the tie plate projections 33 and the angle bar toes 26 are filled by welds of metal 34sV The welded joint between the angle bars and the tie plate eiiiciently prevents rotation through the torsional stresses and provides entire joint.

d slightly from contact Therefore, the

As described, a preferred manner of forming the joint consists in first bolting the angle bars to the rails and subsequently Welding thev toes of the angle bars to the tie plate but it will be clearly apparent that the joint may be formed in other Ways such as by Welding the joint in the shop by pressing the angle bars against a lnandril having the shape of a rail.

Although I have described a preferred embodiment of my invention, it will be apparent that changes and modifications may be resorted to Without departing from the spirit of my invention as expressed in the appended claims.

I claim:

1. A rail joint comprising a tie plate, a rail seating on said tie plate, projections from said tie plate preventing' lateral movement of .said rail, splice bars including inclined faces drawn into engagen'ient with the head and hase of said rail by heilig bolted thereto and wel ded joints between the toes of said splice bars and said tieplate. 4

Q. A rail joint comprising a tie plate, rails seating on said tie plate, projections on said tie plate preventing lateral displacement of said rails, angle bars bolted to said rails, said angle bars including depending toes hav. in g the lower horizontal faces separated from said tie plate, shoulders upstanding from said tie plate and Welded joints between said shoulders and said toes, said Welded joints extending the length of said tie plate.
